Get anim node constant/folded data of the specified type given the identifier. Do not use directly - use GET_MUTABLE_ANIM_NODE_DATA Note: will assert if data is not held on the instance/dynamic. Use GetInstanceDataPtr/GET_INSTANCE_ANIM_NODE_DATA_PTR if the value might not be mutable, which will return null.
